The Fremeau Efficiency Index (FEI) considers each of the nearly 20,000 possessions every season in major college football. All drives are filtered to eliminate first-half clock-kills and end-of-game garbage drives and scores. A scoring rate analysis of the remaining possessions then determines the baseline possession efficiency expectations against which each team is measured. A team is rewarded for playing well against good teams, win or lose, and is punished more severely for playing poorly against bad teams than it is rewarded for playing well against bad teams.

Game Efficiency (GE) is the composite possession-by-possession efficiency of a team over the course of a game, a measurement of the success of its offensive, defensive, and special teams units’ essential goals: to maximize the team’s own scoring opportunities and to minimize those of its opponent. FEI ratings take the season-long GE data and adjust for opponent, placing special emphasis on quality performance against good teams, win or lose.

Other definitions:

SOS: Strength of schedule, based on the likelihood of an elite team going undefeated against the given team's entire schedule.

FBS MW: Mean Wins, the average number of games a team with the given FEI rating would be expected to win against its entire schedule.

OFEI: Offensive FEI, the opponent-adjusted efficiency of the given team's offense.

DFEI: Defensive FEI, the opponent-adjusted efficiency of the given team's defense.

STE: Special Teams Efficiency, the scoring value earned by field goal, punt and kickoff units measured in points per average game.

FPA: Field Position Advantage, the share of the value of total starting field position earned by each team against its opponents.
